Narrative:
The pilot reported that during takeoff, he heard a noise that sounded like "gravel hitting the gear," which continued after landing gear retraction, and prompted a return to the departure airport for a precautionary landing. He stated that while on the downwind leg, the stall warning aural alert sounded, and the stick shaker activated; the pilot used the autopilot disconnect
button to regain control of the airplane.
During touchdown, the airplane bounced and exited the runway, which resulted in substantial damage to the lower forward fuselage. Following the accident, the pilot discovered that he had failed to remove the angle of attack vane cover.

Probable Cause:

Probable Cause and Findings:
